UNITED STATES PATENT OEErcE.

WILLIAM H. WARD, OF AUBURN, NEW YORK, ASSIGNOR TO JOHN A. DODGE,

l OF THE SAME PLACE.

IMPROVEMENT IN HARVESTER-RAKES.

To all whom it muy concern:

Be it known that I, WILLIAM H. WARD, of Auburn, in the county of Cayugaand State of New York, have invented certainl new and usefulImprovements in Harvester-Rakes, of whlch the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, which make part of this specification, andin which- Figure lrepresents a plan or top view of so much of the mechanism for driving aharvester-rake as is necessary to illustrate the invention hereinclaimed; Fig. 2, a view, in

elevation, of the same as seen from the divider side of the machine 5and Fig. 3, a diagram of the same as seen from the rear.

My invention relates to that class of combined reel and rake in Which aseries of independently-hinged rising and falling arms revolves around avertical axis, and is more especially an improvement 011 the patentgranted John A. Dodge, December 3, 1867.

A stand, A, mounted on the main frame, finger-beam, shoe, or platform ofa harvester, supports a central pin, c, around which revolves abevel-wheel, B, driven in any proper well-known way, and carrying adome, C, divided into sections Arms D are pivoted at their inner ends toflanges d, Fig. 3, on a collar revolving with the bevel-wheel, so thateach arm may play freely vertically (as it revolves around the pin) inits respective slot c. The outer ends ofthe arms are bent downward andinward, as shown in the drawings, and carry friction-rollers d on theirouter ends. These rollers traverse in.

contact with guide-rails E F G. Each arm D sintended to carry a rake.

As the bevel-wheel B revolves inthe direction shown by the arrows, thefriction-roller on each arm in succession enters the track bc tween therails E F, and descends to lower the by vertical radial slots c.

rake into the standing grain to sweep it back to the cutters and depositit when severed on the platform. When the latch H remains in theposition shown in black lines in the drawings, each roller, insuccession, rolls up on it The first roller that comes along passesunder the latch and traverses the under side of the rail G, thus holdingthe platform and discharging the gavel. As the gavel is discharged theroller strikes the rail E and rises on it, lifting the latch I, overwhich the rollers usually pass, the latch closing after the rollerpasses.A Any number of rakes or beaters, from one to six, may beemployed.

The slots allow a great range of vertical play to each arm independentlyof its fellows, and yet brace them strongly against lateral strains.

I claim- 1. The combination, as set forth, of the re volvingradially-slotted dome with the indei pendently-pivoted arms.

2. Also, the combination, as set forth, of the radially-slotted dome,the independently-piv-- oted arms, and the guide-rails E, F, andG.

3. Also, the combination, as set forth, of the revolving dome, thepivoted arms, and the guide-rails with the switch-latches, operating asdescribed.

In testimony whereof I have hereunto siba scribed my name. W. H. WARD.
